Abstract
Description
Die Erfindung betrifft einen korrosionsgeschützten Verpressanker, insbesondere einen Felsdaueranker gemäß dem Oberbegriff des Schutzanspruchs 1.The invention relates to a corrosion-protected grout anchor, in particular a permanent rock anchor according to the preamble of the protection claim 1.
Bei Verpressankern, wie sie zur Verankerung von Bauwerken, aber auch als Felsanker eingesetzt werden, besteht das Ankerzugglied in der Regel aus einer Anzahl von einzelnen Zugelementen aus Stahl, die im Bereich der Verankerungsstrecke unmittelbar von erhärtendem Material umgeben sind, während sie im Bereich der Freispielstrecke gegen Korrosion geschützt von einer rohrförmigen Umhüllung umgeben sind, bevor sie im Bereich der luftseitigen Verankerung durch Bohrungen in einer Ankerscheibe hindurchgesteckt und gegen diese Ankerscheibe verankert sind. Die Einzelelemente bestehen häufig aus Stahldrahtlitzen, die ihrerseits zum Korrosionsschutz von Korrosionsschutzmaterial und einem meist aufextrudierten Mantel aus PE umgeben sind. Die Verankerung solcher Litzen in der Ankerscheibe erfolgt durch ringförmige Keile.With ground anchors, such as those used to anchor Buildings, but also used as rock anchors, that exists Anchor tension member usually consists of a number of individual tension elements made of steel, which is directly in the area of the anchoring section dry-set Material while surrounded protected against corrosion in the area of the free spins course by a tubular wrapping are surrounded before they are in the area of the air-side anchorage through holes in an armature disk and against this anchor plate are anchored. The individual elements often consist of steel wire strands, which in turn are used for the corrosion protection of corrosion protection material and a mostly extruded PE jacket. The Such strands are anchored in the armature disk by means of annular wedges.
Für die einzelnen Bauaufgaben werden Ankerzugglieder unterschiedlicher Tragfähigkeit benötigt. Hier haben sich für die unterschiedlichen Einsatzgebiete kleinere Standardanker als zweckmäßig erwiesen, die aus einer geringen Anzahl, meist bis zu zwölf Litzen bestehen. Für die Montage solcher Standardanker sind Standardteile üblich, aus denen die Anker werkmäßig vorgefertigt werden können. Ein Vorteil der Verwendung von Stahldrahtlitzen ist in diesem Zusammenhang, dass solche Standardanker gerollt, also platzsparend, aber dennoch einbaufertig an die Einbaustelle geliefert werden können.For the individual construction tasks become anchor tie elements different Load capacity needed. Here are for the different fields of application smaller standard anchors than proven appropriate which consist of a small number, usually up to twelve strands. For the assembly Such standard anchors are standard parts from which the anchors are made prefabricated in the factory can be. One advantage of using steel wire strands in this context is that such standard anchors rolled, so space-saving, but still can be delivered ready for installation to the installation site.
Andererseits kennt man Großbündelanker, für die schon aus Transportgründen eine Werksfertigung ausscheidet, so dass diese in aller Regel an der Einbaustelle montiert werden müssen.On the other hand, you know large bundle anchors, for those already for transport reasons a factory production leaves, so that this usually goes on the installation site must be installed.
Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, die Herstellung solcher Großbündelanker wirtschaftlicher zu gestalten, jedenfalls zumindest einen Teil der erforderlichen Montagearbeiten werkmäßig ausführen zu können.Against this background, the Invention based on the task of producing such large bundle anchors to make it more economical, at least a part of the to be able to carry out the necessary assembly work at the factory.
Erfindungsgemäß wird diese Aufgabe bei einem korrosionsgeschützten Verpressanker, insbesondere einem Felsdaueranker durch die im Anspruch 1 angegebenen Merkmale gelöst.According to the invention, this task is performed by one corrosion protected Ground anchors, in particular a permanent rock anchor through the claim 1 specified features solved.
Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.Advantageous further developments result itself from the subclaims.
Der Grundgedanke der Erfindung besteht darin, das Ankerzugglied eines Großbündelankers an der Einbaustelle aus mehreren Teilzuggliedern zusammenzustellen, für die zweckmäßigerweise werkmäßig vorgefertigte Standardanker verwendet werden können. Dabei kann für die Montage der kleineren Teilzugglieder der Vorteil der Werksfertigung genutzt werden, während deren Zusammenfassung zu einem Großbündelanker an der Einbaustelle mit Hilfe eines Übergangsrohrs bewerkstelligt wird, in das die Teilzugglieder mit ihren Hüllrohren dichtend hineingeführt werden. Die Einzelelemente der Teilzugglieder setzen sich dann durch das Übergangsrohr hindurch fort, bis sie in der Verankerungsvorrichtung in einer Ankerscheibe in an sich bekannter Weise verankert werden. Damit kann ein Großdaueranker in sehr wirtschaftlicher Weise aus einer entsprechenden Anzahl von kleineren Standardankern an der Einbaustelle zusammengestellt werden.The basic idea of the invention is the anchor tension member of a large bundle anchor to assemble the installation site from several partial tension members, for the expediently factory-made Standard anchors can be used. It can be for the assembly of the smaller partial tension members is the advantage of factory production be used while their combination into a large bundle anchor at the installation site with the help of a transition pipe is accomplished in which the partial tension members with their cladding tubes inserted sealingly become. The individual elements of the tension members then prevail the transition pipe through until it is in the anchor device in an armature disk be anchored in a manner known per se. This allows a large permanent anchor in a very economical way from a corresponding number of smaller standard anchors can be put together at the installation site.
